Insufficient policy enforcement in Navigation in Google Chrome prior to 150.0.7871.115 allowed a remote attacker to bypass site isolation via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Insufficient navigation policy enforcement in Google Chrome prior to 150.0.7871.115 enables site isolation bypass when a user visits a crafted HTML page. A remote, unauthenticated attacker (per CVSS PR:N) can exploit this to read limited cross-origin data, undermining Chrome's core renderer process separation architecture. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target to be running Google Chrome prior to 150.0.7871.115 on a desktop platform and to actively visit an attacker-controlled HTML page - user interaction (UI:R) is mandatory, meaning passive drive-by exploitation without any user navigation action is not possible. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 4.3 (Medium) with vector AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N reflects a realistic but constrained threat: network-reachable, low-complexity exploitation requiring only that the victim visit a malicious page, but limited to low confidentiality impact with no integrity or availability consequence and unchanged scope. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page containing navigation sequences designed to exploit the policy enforcement gap in Chrome's Navigation component. The victim is directed to this page via a phishing email, malicious advertisement, or compromised website. … |
| Remediation | Update Google Chrome to version 150.0.7871.115 or later immediately via Settings > Help > About Google Chrome or through the vendor's stable channel release documented at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_01162222768.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
